B’elana was mostly just angry.

I don't remember shit about B'elana , or much of Voyager characterisation except :

• Janeway : Hardass
• Doctor : fun guy
• Tuvok : generic serious vulcan
• Neelix : obvious comic relief, silly
• Chakotay : Native american guy with a cool face tat

B'elana being mostly angry makes sense as a Klingon and an engineer. each facet isn't known for being sunshine on rainbows, combined, not exactly going to be a delight.

I read B'elana as a point that the chief engineer doesn't always need to be some composed nerd. Even a person with deep anger control issues, with interest in (Klingon) religion, can be a good fit for that position and can stand her ground to a literal Borg.

Plus ofc Janeway + B'elana and + 7 later, meant that most science-related decision were made by a group of women.

But as everyone on the cast, once 7 and doctor were out, the screentime was really compressed 😶

Jeri was local and would appear regularly at local cons :p
